1.	An intranet connected to the internet is often protected by __________(a) a DNS(b) a “brick wall”(c) a “fire wall”(d) antivirusThe question was asked in final exam.My question comes from Digital Multiplexing in portion Multiplexing & Sampling of Bandpass Signal of Analog Communications
Answer» Correct answer is (a) a DNS The explanation is: INTRANET USES internet technologies, but is insulated from the GLOBAL internet. An intranet CONNECTED to the internet is often PROTECTED by DNS.
